===Return random values with the <code>random</code> module===

Use <code>random.choice()</code> to select items at random from a list.

<pre>
>>> import random
>>> my_list = ["terry j.","john","parrot","michael","terry g.", "graham", "llama"]
>>> random.choice(my_list)
'graham'
>>> random.choice(my_list)
'terry j.'
>>> 
</pre>

Use <code>random.sample()</code> to gather a given number of random items from a list. The first argument you pass to the <code>random.sample()</code> function is the set of items you are sampling from. The second argument is the number of items you want to gather from that set.

<pre>
>>> random.sample(my_list,3)
['terry j.', 'llama', 'michael']
</pre>

Use <code>random.randint()</code> to gather a random number from a list of numbers. You specify the list of sequential numbers by passing the starting number as the first argument, and the final number as the last argument. Unlike with <code>range()</code> function discussed below, when you use <code>randint()</code> both the first and last numbers you specify are ''included'' in the set you are sampling from.

<pre>
>>> random.randint(1,10)
8
>>> random.randint(1,10)
3
>>> random.randint(1,10)
10
>>> 
</pre>
